The most important thing that I learned this period was: the all things that we learned before are necessary in the present because the English is like a process.
Tag questions and causatives are some of the topics interestings for me, because the tag questions permit us give and have extra information about a topic or an action that someone did it. And the use of it, depends the intention of who is asking, for example: It´s a beautiful day, isn´t it? the sentence is affirmative so the tag question is negative.
The causatives express that when a person cause to someone do something, we were studying four: have, get, let and make; we use have when we give a responsibility to another person to do something, example: I have my sister does the hosework. We use get when we convince a person to do something, example: Laura gets her husband to travel for vacations. We use let for permission, example: the teacher let us use the dictionary in the exam. We use make when we obligate someone to do something, example: Sofía made her husband cleaned the backyard.
